What is power-to-weight ratio of steam turbine and gas turbine?

there is a mathematical formula to figure the actual power measured in Inchpounds of torque for both types of turbine engines. due to the light weight of the engine and the very high speeds in which they operate they are very efficient compared to other type of power plants generally the rough power to weight ratio of a typical aircraft turbine engine is around 85 to 95% output power compared to the actual weight of the type engine used.the exception to this would be a turbo-fan engine used on high speed aircraft which the power output is measured in footpounds of thrust

What is difference between a geothermal and thermal power plant?
The steam turbine blades to turn creates steam.The steam engine, steam piston Myllng after the turn brings.+++They are both steam-engines. The turbine is purely rotative; the reciprocating steam-engine uses cylinders and pistons.
Where are ratchet mechanisms used?
Ratchet mechanisms used in Gas power plant for Gas Turbine. (like Barring gear in steam turbine).
Steam turbine and internal combustion gas engine for power generation?
Yes, they are both used for power generation
In thermal power generation part the steam came from turbine condensed and again resend to steam conversionIn this part my doubt is why return steam need to be cooled?
The low pressure steam from the last stage of the steam turbine is condensed so that it can be pumped back to the steam raising units at high pressure, as water. You can't compress steam as it would condense in the compressor. The only way to use steam as a gas in a gas turbine would be if it was supercritical, but this would mean operating at temperatures well above the limits for most engineering materials, and steam at these conditions would be very corrosive. This type of reactor cycle using a gas turbine has been considered using helium as the working fluid, and it may be built as the "pebble bed" reactor, or it may not. I think you need to understand more of thermodynamics. Read the Wikipedia entry for the "Rankine Cycle", see link below
What is theConstruction difference between stream turbine and gas turbine?
gas turbines and gas engines are different in mechanic designes uses diffrent liquid for engine we use flemmable gas we use for turbine liquide flemmable but they need air both gas turbines and gas engines are different in mechanic designes uses diffrent liquid for engine we use flemmable gas we use for turbine liquide flemmable but they need air both answer by nailiyoucef05@yahoo.fr I dont think so. Gas engine works as the same principle of a petrol engine. And in gas turbine gas is burned and high velocity gas is passed through the turbine. A gas engine is an internal combustion engine and have no turbines. alamm2@asme.org
What is the defferences between a steam turbine gas turbine?
STEAM TURBINE is a machine for generating mechanical power in rotary motion from the energy of steam at temperature and pressure above that of an available sink. A turbine operated by highly pressurized steam directed against vanes on a rotor.HEAT ENGINE is a physical or theoretical device that converts thermal anergy to mechnical out put.....it converts heat energy into work.
How inefficiencies of compressor and turbine affect back work ratio and efficiency of gas turbine?
Inefficiencies in the compressor of a gas turbine cycle increase the back-work ratio and decrease the thermal efficiency of the gas turbine cycle, since they increase the compressor work.
How does combustion inspection of gas turbine to be carried out?

What is difference between a geothermal and thermal power plant?

What is needed to turn the blade of a turbine?
Wind, water, steam or another liquid or gas.
Where are ratchet mechanisms used?
Ratchet mechanisms used in Gas power plant for Gas Turbine. (like Barring gear in steam turbine).
What Supplies The Mechanical Energy In A Generator?
Any moving fluid can power a turbine. This includes air, water, steam, burning fuel etc. When the fluid strikes the blades of the turbime it transfers energy to the blade causing the blade to move.
How do you produce electricity from biogas?
You can use the bio gas to fuel either a steam cycle generator or a gas turbine.
What is used to turn a generator?
A handle, a pair of pedals, a treadmill, a water mill, a petrol engine, a diesel engine, a wind turbine, a steam turbine, a gas turbine.
What is the definition of combined cycle turbine technology?
Using waste energy in a gas fired electricity generation plant to run a steam turbine
Are airplanes powered by steam engines?
No. They are powered by internal combustion engines. Or by gas turbine jets.
What is the efficiency of thermal power plant?
A modern combined cycle gas turbine/ steam turbine power plant can reach almost 60% efficiency.
